The gas turbine engine in the Army Abrams tank, the Honeywell AGT-1500, is currently experiencing stall and surge related failures of the fourth stage Low Pressure Compressor (LPC). These failures require the removal and overhaul of the tank’s powerpack costing the Army up to $200,000 per event. While all gas turbine compressors run the risk of stalling under non-ideal inlet or operational condi ...

IN THIS PHASE I EFFORT, THE GOAL IS TO DETERMINE THE FEASIBILITY OF CONDUCTING ACCELERATED CORROSION TESTING OF VEHICLES BY SIMULATING 5-10-15 YEARS OF FIELD LIFE IN A COMPUTER CONTROLLED ENVIRONMENT SIMULATION CHAMBER. THE DIFFERENT REQUIREMENTS OF THE CHAMBER, THE TYPES OF ENVIRONMENTS PRESENT IN THE DIFFERENT GEOGRAPHICAL REGIONS, THE CORRELATION BETWEEN ACCELERATED CHAMBER TESTS AND FIELD COND ...

A quality simulation which allows a user to simulate the acoustic emissions in a multi-source environment and then study the effects these conditions have on a set of acoustic sensors would be of great value. As acoustic sensors technology continues to advance with robust algorithms for detection, tracking and identification as well as high performance hardware providing real-time operation, thes ...

Control systems that stabilize the operation of a compressor around the surge line have been demonstrated in controlled laboratory conditions on fixed speed compressors. Jet engine manufacturers are considering this technology for improving engine performance and operability by reducing the compressor surge margins that are currently built into engine control logic. To demonstrate this technolog ...

Ryzing Technologies produced two 100 square-foot prototypes of an Adjustable Reusable Platform System (ARPS) for expeditionary military shelters in a phase I contract.The proposed Phase II effort will advance the design to a production ready state and demonstrate the systems ability to perform in a military environment.Ryzing Technologies will utilize data from potential customers and end users to ...

A NEW AND INNOVATIVE CLASS OF ADAPTIVE COMPUTATIONAL PROCEDURES IS TO BE DEVELOPED FOR THE SPECIFIC PURPOSE OF NUMERICALLY-MODELING COMPLEX FLOWS INHERENT IN ADVANCED HELICOPTER-BLADE DESIGNS. THESE PROCEDURES MAKE USE OF MATHEMATICALLY CONSISTENT ESTIMATES OF LOCAL NUMERICAL ERROR, AND AUTOMATICALLY REFINE OR UNREFINE THE MESH OR INCREASE OR DECREASE THE LOCAL SPECTRAL ORDER OF THE APPROXIMATION ...

This project applies a combination of Artificial Neural Networks (ANN), Genetic Algorithms (GA), and CAD software to the problem of optimum armor design. Previous work for TACOM has established the efficacy of ANN/GA as applied to the problem of 1-D armor design. This new work will extend the concept to full 3-D vehicle geometries (CAD models). The CAD part of the code will handle the 3D data d ...

THE ARMY'S CURRENT TACTICAL COMMUNICATIONS ARCHITECTURE CONSISTS OF THREE VERY CAPABLE BUT INDEPENDENT SYSTEMS: THE ARMY DIGITAL DATA SYSTEM (ADDS), THE MOBILE SUBSCRIBER EQUIPMENT (MSE), AND THE COMBAT NET RADIO FUNCTIONAL SYSTEM (CNR). FULLY AUTOMATED INTERFACES BETWEEN THESE SYSTEMS DO NOT EXIST. IN ADDITION, EACH SYSTEM HAS BEEN TAILORED FOR ONLY ONE TYPE OF COMMUNICATION SERVICE AND IN THE CA ...

It is proposed to demonstrate the applicability of advancement materials, that has been developed for aerospace and military applications, to fuel cell technology to lower cost, increase performance, and decrease weight for future man-portable power systems. MER's advanced C-C composites will be investigated as bipolar plates to decrease weight, increase mechanical integrity, decrease resistivity ...
